While Capstar works fast to kill adult fleas and alleviate a current infestation, a subsequent preventative solution is recommended to prevent future re-infestations from any existing flea eggs and larvae in the environment. If you notice more fleas have found their way onto your dog or cat in the days following treatment, continue treating your dog or cat with Capstar with up to one dose per day.  Important Safety Information Capstar is safe to use in puppies and kittens 4 weeks of age and older, and 2 pounds of body weight or greater.
